The nurse is reviewing laboratory data for a client with epilepsy taking prescribed valproic acid (VPA). The client's VPA level is 40 mcg/mL (50-125 mcg/mL). Based on the laboratory data, the nurse should
- A. Evaluate the client for non-adherence
- B. Instruct the client to skip the next scheduled dose
- C. Assess the client for VPA toxicity
- D. Document the result as within normal limits
Correct Answer: A
Rationale: A VPA level of 40 mcg/mL is below the therapeutic range (50-125 mcg/mL), suggesting possible non-adherence to the prescribed regimen. Skipping a dose is inappropriate, toxicity is unlikely with a low level, and the result is not within normal limits.
